Installer done; goathack fun

I also found some bugs myself when installing LJ on my goathack account. One was htdocs/create_do.bml both referenced a file that was only in ljcom CVS and that it hardcoded /home/lj instead of using $LJ::HOME. Both of those are fixed now.

I should be handing out goathack accounts by the end of the day, if not in the next few hours.
